Additionally, if you want to add a border in ZoomBox like gif shown, refer to the codes below.

double borderWidth = 4;
double radius = 20;

return Scaffold(
  body: Center(
    child: Container(
      decoration: BoxDecoration(
        borderRadius: BorderRadius.all(Radius.circular(radius + borderWidth)),
        border: Border.all(width: borderWidth)),
      child: ZoomBox(
        borderRadius: BorderRadius.all(Radius.circular(radius)),
        width: 250,
        height: 250,
        child: Image.network('https://picsum.photos/250?image=9'),
